Abstract: A heat flow detector is described which measures a predetermined rate of heat flow in its surroundings, the surroundings being in the proximity of a recessed incandescent fixture which is designed to operate safely in the designated environment. Should the operating environment change for the fixture it will be sensed by the heat flow detector. If the operating environment becomes more dangerous so that a fire or other damage may occur the heat flow sensor will turn the incandescent lamp off and on at a slow rate to indicate the changed operating environment. The heat flow detector will cause a slow turn off and on if an oversize lamp is inserted in the incandescent fixture. The heat flow detector will thus prevent an overloaded condition due to an oversize bulb.

Abstract: An all-purpose lamp for use with vehicles. The lamp includes an air impervious housing having a lens formed therein in optical alignment with a bulb carried within the housing. The housing is open at its lower end for receiving a bulb carrier which is movable relative to the housing. Movement of the bulb carrier controls the on-off operation of the lamp.

Movement of the slide relative to the lamp housing will effect a corresponding movement of the bulb carriage, thereby moving the bulb in to and out from engagement with a pair of electrical contacts supported within the upper portion of the lamp housing. In this manner, illumination of the lamp is controlled by moving the slide to effect a corresponding movement of the bulb carrier into engagement with the electrical contacts coupled to the vehicle power supply.
